Setting the Cursor

I did search and try this section of code; but the cursor did not change?

BeginWaitCursor(); // display the hourglass cursor
// do some lengthy processing
EndWaitCursor(); // remove the hourglass cursor

This was for a Visual Studio 2005 MFC C++ Dialog application.

I just want an hourglass for a few minutes while some processing is taken place.

Many thanks,

Andy.

I think it should work can you paste your code here ?

Also try using LoadCursor(...)

// Set hourglass cursor:<br />
BeginWaitCursor();<br />
	while (!g_pRecordset->GetadoEOF() /* && g_nLineCounter < 1000 */)<br />
	{<br />
		// Obtain the MessageDisplayName<br />
		g_TheValue = g_pRecordset->Fields->GetItem ("MessageDisplayName")->Value;<br />
		g_szMessageDisplayName.Format("%s", (char *)_bstr_t(g_TheValue));<br />
		j++;<br />
		ProcessMessages();<br />
	} <br />
	EndWaitCursor();<br />
	output.AppendFile(g_szFileName, m_lineData);

Nothing happens with the cursor, I use ProcessMessages() to pump the message queue so that I can update a listView that is being populated.

Any suggestions?

Is there any reason not going for CWaitCursor ?
You code would be modified like this,

// Set hourglass cursor:
CWaitCursor wait;
while (!g_pRecordset->GetadoEOF() /* && g_nLineCounter < 1000 */)
{
// Obtain the MessageDisplayName
g_TheValue = g_pRecordset->Fields->GetItem ("MessageDisplayName")->Value;
g_szMessageDisplayName.Format("%s", (char *)_bstr_t(g_TheValue));
j++;
ProcessMessages();
} 
output.AppendFile(g_szFileName, m_lineData);

You only need to construct its object.

Although this code may well work, it's also possible that the ProcessMessages() call could cause the cursor to return to the standard arrow.

If that is happening, add a
wait.restore();
after the ProcessMessages() call.

Hope that helps.

I wanted to add this in my post,too. Which is mentioned in MSDN standard example.
But avoided, for sake of confusion.

Yes, you can always restore wait cursor with Restore call.

SetCursor(...);
You can also change the cursor with your methodology. Did you check whether the lines of code that lie with in the
BeginWaitCursor();
// Some code here.. Take some time here
EndWaitCursor ();

Block are consuming that much of time for you to see the effect on your screen.

Somethings seem HARD to do, until we know how to do them.

Manipulating user input

21-Sep-06 21:48

Hi guys

I have been trying to make an app that takes simple user input then modifies the memory of some process acording to what the user typed using the writeprocesssomething method but the prob is that i need to modify an array for that as well. Lemme give an example:
I have made a CEdit variable and called it m_bytes(which contains the number of bytes to be written) next i made another variable and called it m_writetoprocess(contains the stuff to patch).

The dialog looks like this:

Bytes: 3

Patch with: 90908D

so now the array that i have made in the code will look like this:

array[3] = {90908D};

but u cant modify the memory that way so how do i change the user input so that it looks like this:

array[3] = {0x90, 0x90, 0x8D};

And one more thing is it possible to read binary data using readprocessmemory then display it in ASM code for ex if i used readprocessmemory like this:

ReadProcessMemory(hProcess, (VOID*)0x12A0D856, &memoryread, 4, 0};

then, lets say, that the memoryread variable contains this binary memory code: 74653298 now how do i change this code to ASM so that it looks like this: JMP 893256 ?

Please help me with this as i have been looking for an answer for ages now without success!

Thanks in advance

While getting the input, haldleWM_CHAR and store the individual key press into the i.e : array[i]; i++.

Or read the chars one by one in the CString and store it in the array.CString::Mid(start,count) usefull for you.

hi,

Given a window handle, is there any way we can know what it consists of
like child windows, Window title, menu items etc.

It would be very helpful if anyone can point to the API s or the MSDN documentaion, so that i can the use them in my win32 application.

Thanks in Advance,

See EnumChildWindows(...)
Also:
typedef struct {
DWORD cbSize;
RECT rcWindow;
RECT rcClient;
DWORD dwStyle;
DWORD dwExStyle;
DWORD dwWindowStatus;
UINT cxWindowBorders;
UINT cyWindowBorders;
ATOM atomWindowType;
WORD wCreatorVersion;
} WINDOWINFO, *PWINDOWINFO, *LPWINDOWINFO;
GetWindowInfo(...)
This gives some information about a window's handle that you have.....
Do not know whether this would suit your needs or not exactly?

and passing the application's HWND to GetWindowText() would retun you the window caption(title).

for this purpose you can use
strcpy(char *,CString)
